Diagnostic Procedure

Step	Inspection		Action
1	Inspect the operation of the door glass by operating the power window main switch. Is the manual operation normal?	Yes	Go to the next step.
1		No	Inspect the following parts, and repair or replace. Power window main switch (See POWER WINDOW MAIN SWITCH INSPECTION ). Power window motor (See POWER WINDOW MOTOR INSPECTION ). Battery (Low voltage)
2	Inspect the operation of the door glass by operating the power window main switch. Does the door glass operate in auto?	Yes	Go to the next step.
2		No	Perform the power window initialization procedure. (See POWER WINDOW INITIALIZATION PROCEDURE ).
3	Does the door lock/unlock normally?	Yes	Inspect the wiring harness between the power window main switch and the BCM. If there is any malfunction, repair or replace the applicable part.
3	Does the door lock/unlock normally?	No	Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION ).

Step	Inspection		Action
1	Inspect the door lock/unlock operation using the transmitter. Does it operate normally?	Yes	Inspect the following parts, and repair or replace. BCM (See BODY CONTROL MODULE (BCM) INSPECTION ). Keyless control module (Vehicles with advanced keyless system) (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ).
1		No	Go to the next step.
2	Inspect the open/close condition of the doors and the liftgate. Is the reason why they do not lock/unlock because a door or the liftgate is open?	Yes	System is normal (Does not operate when a door or the liftgate is open).
2		No	Go to the next step.
3	Verify whether the key is in the steering lock. Is the reason why they do not lock/unlock because the key is inserted in the steering lock?	Yes	System is normal (Does not operate when the key is inserted in the steering wheel lock)
3		No	Go to the next step.
4	When the lock/unlock operation does not operate for reasons other than the above Steps 2 and 3.	Yes	Inspect the following parts, and repair or replace. Keyless control module (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ). Wiring harness between keyless control module and BCM.
4		No	Reinspect for malfunction recurrence. If the malfunction is not corrected, repeat the procedure from Step 1.

Step	Inspection		Action
1	Verify the door lock/unlock operation by operating the request switch. Does it operate normally?	Yes	Inspect the following parts, and repair or replace. Keyless control module (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ). BCM (See BODY CONTROL MODULE (BCM) INSPECTION ).
1		No	Go to the next step.
2	Verify the open/close condition of the doors and the liftgate. Is the reason why they do not lock/unlock because a door or the liftgate is open?	Yes	The system is normal (When any door or the liftgate is open, the system does not operate).
2		No	Go to the next step.
3	Verify the start knob position, or if the key is in the steering lock. Is the reason why the door lock/unlock does not operate because the start knob is in a position other than LOCK, or the key is inserted?	Yes	The system is normal (When the start knob is in a position other than LOCK, or the key is inserted in the steering lock, the system does not operate).
3		No	Go to the next step.
4	The door lock/unlock does not operate for reasons other than Steps 2 and 3 above.	Yes	Inspect the following parts, and repair or replace. Keyless control module (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ). Wiring harness between the request switch and the keyless control module.
4		No	Reinspect for malfunction recurrence. If the malfunction is not corrected, repeat the procedure from Step 1.

Step	Inspection		Action
1	Inspect the door glass operation by operating the power window subswitch (passenger's). Does it operate normally?	Yes	Go to the next step.
1		No	Inspect the following parts, and repair or replace. Power window subswitch (passenger's) (See POWER WINDOW SUBSWITCH INSPECTION ). Power window motor (See POWER WINDOW MOTOR INSPECTION ). Battery (Low voltage)
2	Inspect the door glass operation by operating the power window subswitch (passenger's). Does it operate in auto?	Yes	Inspect the wiring harness between the power window main switch and the power window subswitch (passenger's). If there is any malfunction, repair or replace the applicable part.
2		No	Perform the power window initialization procedure. (See POWER WINDOW INITIALIZATION PROCEDURE ).

Step	Inspection		Action
1	Operate the door glass in auto/manual by operating the power window main switch/power window subswitch (passenger's). Does the door glass stop before fully opening/ closing using either operation?	Yes	Inspect the following parts, and repair or replace. Power window main switch (See POWER WINDOW MAIN SWITCH INSPECTION ). Power window subswitch (passenger's) (See POWER WINDOW SUBSWITCH INSPECTION ). Power window motor (See POWER WINDOW MOTOR INSPECTION ). Battery (Low voltage) Door glass (Installation condition)
1		No	Go to the next step.
2	Inspect the operation of the door glass by repeating Step 1 above. Does the door glass stop before fully opening/ closing while in auto operation?	Yes	Perform the power window initialization procedure. (See POWER WINDOW INITIALIZATION PROCEDURE ).
2		No	Go to the next step.
3	Open the door glass by operating the transmitter. Does the door glass stop before fully opening?	Yes	Inspect the following parts, and repair or replace. Keyless control module (Vehicles with advanced keyless system) (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ). BCM (See BODY CONTROL MODULE (BCM) INSPECTION ).
3		No	Go to the next step.
4	Close the door glass by operating the transmitter. Does the door glass stop before fully closing?	Yes	Inspect the following parts, and repair or replace. Keyless control module (Vehicle with advanced keyless system) (See KEYLESS CONTROL MODULE INSPECTION[ADVANCED KEYLESS SYSTEM] ). BCM (See BODY CONTROL MODULE (BCM) INSPECTION ). Keyless entry system signal reception error (outside operation area, radio signal interference)
4		No	Reinspect for malfunction recurrence. If the malfunction is not corrected, repeat the procedure from Step 1.

Step	INSPECTION		ACTION
1	By operating a power window main switch / power window subswitch (passenger's), operate the door glass. Does the door glass mis-reverse?	Yes	Inspect the power window motor and repair or replace it. (See POWER WINDOW MOTOR INSPECTION ).
1		No	Inspect the following parts and repair or replace them. Power window motor (See POWER WINDOW MOTOR INSPECTION ). Battery (brownout) Door glass (improper installation) NOTE: Depending on the temperature, battery, and voltage condition, the door glass may mis-reverse.

NOTE
Depending on the temperature, battery, and voltage condition, the door glass may mis-reverse.

STEP	INSPECTION		ACTION
1	Inspect if malfunction is in operating by transmitter	Yes	Inspect the transmitter.
1	Inspect if malfunction is in operating by transmitter	No	With keyless entry system Go to Step 3. With advanced keyless system Go to the next step.
